The On-one prototype fat bike quite extensively recently. I'm really loving it. There will be a few changes before production but nothing major. The Surly Nate's have been fantastic and are already opening up the potential of the bike, and Fatbikes as a whole. It's going to be an interesting year.I'm about to strip the bike down and rebuild it for the Rovaniemi 150 next month. After that it's being lent out to be taken out to Siberia. Guess I'd better find something else to ride for a while!
